Flask get post return返回字典内容

1， 返回str

from flask import Flask,request
app = Flask(__name__)
@app.route('/',methods=['GET','POST'])
def get_method():
    return "hello world"

if __name__ == '__main__':
    app.run(host='127.0.0.1', port=5000, debug=True)

 

 2， 读取GET请求

from flask import Flask,request
app = Flask(__name__)
@app.route('/',methods=['GET','POST'])
def get_method():
    print(request.args.get('name'))
    print(request.args.get('age'))
    return request.args.__str__()

if __name__ == '__main__':
    app.run(host='127.0.0.1', port=5000, debug=True)

 3， 返回dict

from flask import Flask,request
app = Flask(__name__)
@app.route('/',methods=['GET','POST'])
def get_method():
    #request.args.get 获取链接中的值
    Name = request.args.get('name')
    Age = request.args.get('age')

    dict1 = {}

    dict1['姓名'] = Name
    dict1['年龄'] = Age

    return dict1  # return支持字典返回等，不支持list返回

if __name__ == '__main__':
    app.run(host='127.0.0.1', port=5000, debug=True)

GET

POST

4，通过request.method的方法来判断网页的提交方式

from flask import Flask,request
app = Flask(__name__)
@app.route('/',methods=['GET','POST'])
def get_method():
    if request.method == 'GET':
        return '123'
    else:
        return '321'

if __name__ == '__main__':
    app.run(host='127.0.0.1', port=5000, debug=True)

如果是get请求返回123，否则返回321
